Is it okay for a rat and dragon to get married after knowing each other for less than a year long?

My fiancé is a dragon and he proposed just months after we've been together and my friends and family tell me I'm crazy to have said yes. I don't think waiting would do anything but slow things down for us because my fiancé, (the dragon), and I, (the rat), know that we are completely compatible in every way. We're not rushing things, but my everyone around me tells me although we are perfect for each other, we should wait.
